Real Housewives superfan Rihanna poses up with Beverly Hills star Kathy Hilton at her lavish Met Gala afterparty ... with A-list guests like Megan Thee Stallion and Mary J. Blige 

Rihanna served as hostess for one of the Met Gala's most coveted afterparties on Monday night. 

The 33-year-old Fenty Beauty creator is a long time Real Housewives super fan and she happily posed for a quick snap with Real Housewives of Beverly Hills star Kathy Hilton.

A bevvy of stars attended RiRi's soiree at DAVIDE in New York City, including Megan Thee Stallion, Mary J. Blige, Posh and Beck's son Brooklyn Beckham, soccer star Megan Rapinoe and Ozark's Julia Garner. 

Rihanna was seen perching on a white banquette smiling while cuddling up for a photo with Kathy Hilton.

The mother of Paris and Nicky Hilton shared the adorable snap to her Instagram account with the simple caption: 'Fun night in NYC at @badgalriri’s party! ❤️'

Kathy appears as a 'friend' of the Housewives in the Beverly Hills installment of the Bravo reality series, alongside her sister and longtime cast member, Kyle Richards.

RiRi has never been shy about her love for series and counts herself a regular watcher of all the drama - and a friend to some of the stars.

In July, Rihanna effectively had the last word in some petty RHONY drama after her name was brought up by Leah McSweeney during bar blowup with Ramona Singer.

The Savage X Fenty founder's Instagram post threw some subtle shade at Ramona for being judgmental about Leah's clothing line, Married to the Mob, of which Rihanna is a big fan.

Meanwhile, the star turned heads after the Met Gala in her party garb sporting a simple short-sleeved black top knotted at her waist with a diamond brooch, paired with a slinky black sheer skirt and beaded sheer headscarf.

She was in good company when it came to icons of the music industry. Legendary singer Mary J. Blige was spotted at the event in a slinky blush bodycon dress with cutouts at her waist and hips. She rocked oversized gold earrings and teased blonde curls.

Hip hop's rapper of the moment, Megan Thee Stallion set pulses racing in a skin tight long sleeve chiffon yellow mini dress with long straight hair extensions.  

The event was arranged by nightlife mogul Richie Akiva, the New York Post's Page Six reports.

Following last year's cancellation and delays to this year's event - which is traditionally held in May - sources claim hopeful guests had been 'begging' for an invite to Rihanna's soiree, at the expense of other events.

'One promoter was putting tens of thousands on the table in offers,' an insider told the publication. 'But everyone turned it down just to be at Rihanna’s party.'

Lil Nas X, who made his Met Gala debut Monday, was seen dressed down heading into the exclusive bash. 

Earlier, Rihanna was fashionably late to fashion's biggest night out on Monday with her rapper boyfriend A$AP Rocky by her side. 

According to Vogue, Rihanna and A$AP Rocky were the final guests to arrive.

The songstress ended up on both best and worst dressed lists as she climbed the steps of the Metropolitan Museum of Art in a a billowing Balenciaga coat dress.
